The orangespotted filefish (Oxymonacanthus longirostris) belongs to a group of fishes with a rough skin that actually feels like a file. Filefishes are closely related to triggerfishes and, like their cousins, they are poor swimmers. The orangespotted filefish is native to the coral reefs of the Indian and Pacific oceans. This species feeds reaches a maximum size of 5 inches (12centimeters) and feeds exclusively on acropora coral polyps. It absorbs and chemicals from the coral which helps to protect it from predators by making it smell bad.
